摘要
近年来,各大城市正大规模开展地铁建设,为了减小地下交通施工对地面交通的干扰,地铁车站的建设方式逐渐由明挖向暗挖转变.然而,暗挖地铁车站的断面较大,且位于地下,多采用竖井或斜井进入车站,如何安全、快速完成斜井转正洞进入车站主体施工,是施工控制的重点、难点.该文以某地铁暗挖车站为例,就斜井转正洞的传统施工方法进行了阐述,并对传统施工方法存在的缺点进行了分析,在此基础上提出新的施工方法,并对相关施工技术进行了总结.
Abstract
In recent years,major cities have been carrying out subway construction on a large scale.In order to reduce the interference of underground traffic construction with surface traffic,the construction method of subway stations has gradually shifted from open excavation to underground excavation.However,the cross-section of subway stations excavated underground is larger,and they are often accessed through vertical shafts or inclined shafts.How to safely and rapidly complete the transition from inclined shafts to vertical shafts for access to the main body of the station is a key and challenging aspect of construction control.Taking a certain subway underground station as an example,this paper elaborates on the traditional construction method of reverting inclined shafts to vertical shafts,analyzes the shortcomings of traditional construction methods,proposes new construction methods based on this analysis,and summarizes relevant construction techniques.
